Answer:
1=(4/4)*(4/4)
2=(4/4)+(4/4)
3 = (4+4+4)/4
4 = 4 + (4-4)*4
20=4 × (4/4 + 4)
20=4 × (4/4 - (-4))


Step-by-step explanation:
The x is a multiplication sign not a variable, I hope this right. Good luck, I am so tired.

Step-by-step explanation:
x = 3 or x = 1
note that log 5 is usually taken to mean
5
using the law of logarithms
logx - logy = log (
)
the right hand side can be expressed as
log 10000 - log 16 = log (
) = log 625
divide both sides by log 5
x² - 4x + 7 =
= 4
subtract 4 from both sides
x² - 4x + 3 = 0 ← in standard form
(x - 3 )(x - 1) = 0
equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 1 = 0 ⇒ x = 1

15(10.5)(4.5) = 708.75
